Bilateral Repetitive Transcranial Magnetic Stimulation for Auditory Hallucinations Results

Bilateral rTMS Clinical Trial for Persistent Auditory Hallucinations Results for a Terminated Study

The primary purpose of this study was to conduct fMRI neuroimaging studies prior to and subsequent to the rTMS intervention. The intent was to ascertain changes in regional brain activation and connectivity that most robustly predict level of improvement in auditory hallucinations elicited by bilateral rTMS as assessed by the primary outcome variables.

This study is an extension of previous clinical trials (NCT00308997 and NCT00567281) that were initiated in 2006. This study record provides the results for the amended study NCT00567281 (originally called a 'third arm') that was discontinued following the passing of Dr. Ralph Hoffman. The primary purpose of the study was to conduct fMRI neuroimaging studies prior to and subsequent to the rTMS intervention. The intent was to ascertain changes in regional brain activation and connectivity that most robustly predict level of improvement in auditory hallucinations elicited by bilateral rTMS as assessed by our primary outcome variables. It was hoped that this combined fMRI/rTMS study would provide critical new insights into the neurobiological basis of auditory hallucinations.

The results presented are what was summarized following Dr. Hoffman's passing and were compiled by Dr. Philip Corlett.
